Some element of the third level drop-down Menu is invisible

APEX 4.2

Oracle 11i

area type: list

list template: drop-down menu

Requirement: I created the menu list with level 3 model, but found that some element of the third level is invisible, sometimes, someone has experienced this problem?

How can I show the whole issue?

Better compliance

Thank you very much, you are right, it worked when I changed the target type of URL without a target.

But the new problem is that cannot save changes implemented which target URL, it was recovered on the page target type in the application to the next time. How do I do? Like a menu, I have to put the page number to the target.

and why target page type the application cannot show normally?

This is because (at least in the example you provided) to two factors:

  • A 'feature' the theme 21 Pull Down Menu model list, which seems to be so designed as not to display a link to the current page. The current definition of model sublist will render an image of separator rather than the list entry/link:

  • Your entries of the list all link to the same page.

So to determine which model of list item to apply using the list input parameter current that current page is the target by default, APEX motor sees all of the entries in the form of links to the current page and presents them by using the current model sublist list item template as a separator.

All of your entries of the list really related to the same page? If so, why is this? What you trying to do? There may be other ways to address the issue that you have not considered.

If you really must use a dropdown menu with multiple links to the same page here, then there are two options:

  • Continue to use the list template Pull Down Menu provided, but put in place a framework of Expression PL/SQL or SQL query to determine the current list entry.
  • Create a copy of the Pull Down Menu model list and change the current model sublist definition so that the list entry appears in fact.

    Hello everyone, I am trying to familiarize themselves with the location with flex, I created my own files in use, files (.properties) and a simple application that works.  It uses a dropdownlist control to allow the user to choose what language to see.

    Thank you!

    You need to create something like that

    ARR:ArrayCollection = [{id: 'en_US', Label: 'English'}, {id: 'en_US', Label: 'French'}]

    so, you can use internally as locale en_US but dropdown will show English...

  • Problem with the help of drop-down menu in the lifecycle Designer 8.0

    Hi Chomp,

    When in design mode:

    If you highlight the Hiarchy palette dropdown, it remains highlighted? or the flip pointing to someother object?

    If you click on it directly in the workspace. It shows "drop" in the palette object for the "Type"?  or something unexpected?

    If she will not be highlighted or say something unexpected, it is your question - I suspect by copying and pasting the drop something has gone wrong.

    If so, you must get rid of these bad objects. My experience is that if you have bad objects you can have difficulty to remove directly and may need to remove the parent (the tablerow or subform that they have).

    I'm very curious to know if this is your problem. Please post an update when you get a chance.

    Good luck

    Stephen

    P. S.

    Go slowly when you copy and paste - make sure you that Designer is finished with this operation before starting the next batter - it takes more time than you may realize. Additionally, make sure that the object palette indicates that you are where you think you are, before pasting. After you are done paste an object, Designer has an odd routine indication of the Master Page as object type when its done. If so, set the focus again for which you want to paste, before sticking another menu drop down always in your Clipboard. If your drop down boxes in rows in the table, think about copy and insert any lines containg your DDL

    Finally, 73 DDLS 73 points? Wow! IMHO, 73 points is too much for a user. Consider using the preOpen and script, the filling of the DDL event. If you do this then you can fill in the with a shorter list once the user has made some choices. Just a thought.

  • Hide the subform when drop-down menu is null

    I'm doing a subform 'hidden' when a drop-down list object is null and 'visible' when the drop is not null. I use the following script:

    If (this.rawValue = null) {}

    xfa.resolveNode ("Subform3. #subform. . GroupLeader presence') = 'hidden ';

    }

    else {}

    xfa.resolveNode ("Subform3. #subform. . GroupLeader presence') = 'visible ';

    }

    Script does not work. Is it wrong or have I got it in the case of bad? (Form ready)

    Thank you

    Hello

    To start I place this script to the output of the dropdown event.

    You also have a subform without name, which requires you to solve the node. This is inefficient, so if you name the subform, you will be able to use a simple reference (see: http://assure.ly/kUP02y).

    The main problem with the script is that when you test equality (in the if/else statement), you must use a double equals sign (==).

    So, if you have renamed the subform "Subform4:, the script would become:

    if (this.rawValue == null) {
         Subform3.Subform4.GroupLeader.presence = "hidden";
    }
    else {
         Subform3.Subform4.GroupLeader.presence = "visible";
    }
    

    Hope that helps,

  • OfficeJet Pro 8600 appears twice in the selection of drop down menu printer with each of the different names.

    Hello!

    I recently acquired an Officejet Pro 8600 and immediately connected to my network wireless as stated in the manual. No other type of connection has been used beforehand and the operating system is Windows 7 64 bit.

    After that the installation of the printer driver appears twice each time that a program asks me to select a printer from the drop of the printing devices in the typical menu of preparation of printing.

    There is an entry for "Officejet Pro 8600 (network)" and something in the sense of 'HP95CDN' (Officejet Pro 8600). I can't remember the exact names off the top of my head, but it is the name of the printer with the 'network' in brackets in one case and a kind of shortcut ID printer with full name in parentheses in the other case.

    According to the program, one of the options gives the desired impression while the other simply causes a queue of indelible impression for the name of the unit in question that is stuck to a few KB of data transmission.

    Usually printing works with the device with the identification of the printer in its name, but I recently had a case where with LibreOffice printing only works with the other choice.

    Can someone explain to me exactly means?

    See you soon,.

    Pete

    Direct entry Wireless will be visible under menu so direct wireless is on... However, since you are able to print another icon (not the network icon) I assume direct wireless is off coz you will not be able to print from wireless directly on the printer if you are connected to the router.

    I believe that the icon of the printer (not the network icon) has a port WSD assigned and is automatically detected by the operating system and installed.

    Go to service window and check if you have any input that says function Discovery Provider Host and see if it is started. Try to stop the service, and remove the icon of the printer (not the network icon) in the print server properties.

    Restart the PC and check if the icon comes back or try to uninstall and reinstall

  • Drop-down menu used with anchor on the long table of data links

    Hello

    I have a page on our site where we used a drop shape with anchor tags to let the visitor easy access to specific locations within a long table of data on the same page. Recently, I noticed that the anchors are walking around is no longer the tags in the page but only the beginning of the table anyway. I don't know if over time a few additional codes may have been added to the page that is not in conflict with the form of drop down menu, or if it's something else. I've been agonizing about this for awhile now and unable to fix. I'm hoping a new set of eyes will revisit the issue. the url is http://www.vectron.com/products/saw/saw.htm

    Thank you

    Looks like there are a good number of errors html on this page, some of them have to do with using the code of the named anchor.

    Looks like you have placed the anchors between the openingand the child of the opening. Content cannot go there, move them in theTags and see if that helps.

    It could be something else however, html errors are one of the main causes of the problems of display/functionality. Visit the validator to http://validator.w3.org to clean up your errors. If you work with the code clean and correctly positioned anchors, after return and we can take a closer look.

  • Drop-down menu is hidden behind the elements

    Hello

    I have a right to 2 containers after another. Drop-down menu is in the first. When I want something to choose in the drop-down menu, he hides behind the elements in the second container.  How can I make this drop in the front, when the seecting elements?

    In my application, I also noticed that when I didn't use a drop-down list ScrollView did disappear after the elements below the drop-down list. Then when I used a ScrollView around all elements, it has been resolved.

    A drop-down list in cascades infact do not come on the top items. It expanded just himself and all the elements under the menu drop-down get pushed down. When the bottom is reached, items below, that the drop cannot be pushed more, so the drop-down list will appear behind items.

    When you use a scrollview, the items in the drop-down list may get pushed too far below is necessary because the window is not limited to the screen.

    I hope that was a little bit useful.

  • Drop-down menu in the table of cells - how to develop across the width of column?

    Hello!

    A customer migrate their 2 400 forms of old JetForms as PDF (LiveCycle Designer) and would like to keep the same functionality, so that it is used in the old platform. However, some of the old tool features do not seem to be present in LiveCycle.

    Suppose that a drop down menu in a table cell, containing the elements whose lengths are larger than the column of the table. In JetForm, when you open the drop-down menu that spans the columns to display all of its content, do not cut the contents of the drop-down list.

    I tried this in LiveCycle, but the drop down menu gets cut and its content is limited to the column in the table (where the drop-down menu below) width.

    Is there a way to bypass this limitation, even if I use scripts?

    Thank you for all the ideas!

  • Some web features working not (buttons, drop-down menus, etc.)

    I have recently reinstalled windows 7 on my machine, and since I had problems with firefox. I had the same exact configuration installation and firefox before reinstall as far as I can remember, and I've not had the problem then. I tried the current version and the beta version of firefox.

    Basically, on some Web sites, there are some things that does not work as it should. Some buttons does nothing, some drop-down menu nothing done, image resizing works not etc.. Maybe it has something to do with javascript? Although most of the javascripts appears.

    Here's an example: on this site: http://www.bitcoinx.com/profit/
    'Reset' and 'Calculate' blue buttons does not work. The effect of the passage of the mouse works, but when I click on them, absolutely nothing happens.

    Rather a general answer I'm afraid, because I don't see an obvious problem & solution:

    1. Note for any problems with the sites that it is always worth to erase cookies from this site and to cache How to clear Firefox cache &delete cookies to remove the information from Web sites is stored on your computer
    2. Try in safe mode (see questions to troubleshoot Firefox in Safe Mode) that is accessible from your Firefox Button. (but at this stage try not yet reset)
    3. If the above does not help then try the Firefox reset, but be aware, you will lose the open tabs, extensions and preferences, you may need to favorite things first if you can find them still see Firefox Refresh - reset the settings and Add-ons

  • What/where is the drop down Menu to the Menu of the histogram in Lightroom?

    The tutorial that you shared is for Photoshop.

  • Drop-down menu does not when the navigation bar collapses in rocker

    Hi all

    I use 3 "bootstrap" on the site below and I have some questions when the navigation bar collapses in rocking, as it seems to stop the drop down menus to work. When you tap or click the drop-down menus, the menu closes just, once again.

    Can someone tell me please on this?

    http://www.clockdoctors.co.UK/test/index.html

    I apologize to this topic. I didn't see that earlier post, I obviously had a blond moment.

    OK, so I think that I fixed it!

    I first tried to remove the script ' ' to see what would happen. Which translates to the stop of the page class 'scrolling' to work, but then allows the drop-down menu to work as it should, as you say.

    I then put this script, but removed this piece of code in the file "agency.js".

    Close the sensitive Menu on the Menu, click on item

    $('.navbar-effondrement_ul_li_a').click (function () {}

    $('.navbar-toggle:visible').click ();

    });

    and now it works fine!

  • Remove the default value drop-down list

    I am currently working with Acrobat Pro XI version. I want to know if it is possible to remove the default value in a drop-down list.

    When the list less than 4 elements, it is possible to deselect the default value by pressing the spaces below. However, when there are no more elements, it is more possible.

    I read that you need to include white space as a component in the list of elements, however, then you will see an empty list item when people work with the pdf that is not preferable.

    So, nobody how to remove the default value in a drop-down list?

    Thank you!

    OK, I found a perfect solution to my problem by using FormsCentral for Acrobat. Here's what you need to do:

    Step 1:

    -Open FormsCentral

    -Create new form (choose the blank form)

    -Click the drop-down menu to create a new drop-down list

    -Fill out the items in the list by clicking on the timeline (you can also add a label if you want)

    -Click on: file > save as PDF form...

    Step 2:

    -Open the PDF saved (you will now see a blank pdf with a menu drop-down)

    -Click on: Tools > forms > Edit Form (when a pop-up window indicates that you should save a copy of the document in order to make changes, press 'Save a copy' and open the file with Acrobat pdf copy)

    -Select the drop-down list, the drop-down list to copy and paste it into the desired document

    Now you have a drop down without a default choice. Remember that you can not change the items in the drop-down list, because we will choose a default choice and you must use the copy pdf file once again. As long as you do not click on a list item, it is not choose a default choice.

    It is not a perfect solution, but it works for me.

    Good luck and thanks!
