Complex drop-down list

I want to implement a drop-down list with 20-50 points, and each line item will have a fairly complex together information to display, including images and text loaded from the web, text and images loaded from the device.

I searched a bit on the forums and noticed people had two main approaches.

Custom VerticalFieldManager or a custom ObjectListField where they replace the drawListRow function.

With regard to the application of something as they are only two options I have? And in terms of performance, which one would be better to implement a list 20 + points, where each line has a fairly complicated layout?

Thank you.

I use the objectlistfield in virtually all applications, so I wrote my own extension of the listfield class. It offers many advantages, for example to add a vector, define a vector, customization of the color of the setting to the point or the extraction of the selected object. can not share the code of course, but it is otherwise difficult to perform and easy to improve them if necessary.

I would recommend that you take an hour or two and implement an objectlistfield as desired, can save a lot of time later.

With regard to the different heights: you can use the hidden setRowHeigt (index, height) method, but I wouldn't recommend it.

Better adapt to the requirements

  • Selection in the drop-down list box determines the text to display in another box - ideas?

    Hello, my name is Zac.  I spent a lot of time trying to figure this one out for myself, but I couldn't find what I needed.  A few threads looked promising, but I realized that they only apply to the LiveCycle.  Many other threads link to discussion 2006 Thom Parker on this subject, but it is very advanced and I feel that what I need is not as complex as the solution he proposes.  I've never used Adobe Acrobat until a few weeks ago, but with the help of Bernd Alheit and George Johnson I managed to create a document with fly-out help windows and scrolling lists and radio buttons which dictate the choice.  It's great and it works.  The last thing I have to do is to create a text box (or some kind of box) which will display a pre-written block of text based on the user choice in another area (a drop-down list box).  Like this:

    image for forums 2.PNG

    I wish, it is also easy to create because it draw a picture of him!  If the user selects "Algebra 1", for example, a specific description display below.  There are a lot of courses and descriptions, and the descriptions are long enough (as shown).  It is not necessary for the user to make changes to the description - in fact, which would be terrible.  But I would like to be able to copy text from it and paste the text in another area of text on the same page.

    Thank you very much, all those who have ideas please share them! Again wild guesses. I learn from all this.

    This involves using a script. If you want to write the code yourself read this tutorial:

  • Drop-down list - how to use event handler?

    I can't with setting the readonly (via Javascript) in the adjacent text box property to my drop-down list when the index value is a number.

    I tried to use MouseUp and MouseDown OnBlur even... but the readonly does not always get the value true or false,.

    This could be a timing problem? The text box that I am trying to control is the control tab order in the list of controls for this page.

    This same logic works very well in the MouseUp handler for checkboxes. So I was just wondering if it is a bug or should change the my implementation to accommodate drop-down lists? For example, should I move the logic to the handler Enter the text box instead? An own eventhandler of the control set read-only when it is the active form field does

    -Not quite (it comes after the events of mouse, but before the blur event),

    but it should do for your application. The process of the event is complex. You can

    -C' is correct, although it is not a bad idea to do it explicitly anyway.

  • Nested drop-down lists (3) spontaneously corrupt

    I have a project in Robohelp X 5 which worked well. A topic is incredibly dense (very complex procedure) and includes a drop-down text box nested three layers (layer one contains several drop-down lists, and all of them contain some institutions).

    Converted Robohelp 7 project, seemed to convert well. Audited the spelling/grammar on the printed and discovered documentation that this topic has been altered. The first layer contained the * links * layers second, but the * content * second layers had migrated upwards in the first layer.

    I have rebuilt the subject (well, part of it), digging in the third layer. When I saved the topic I stepped back to the main view of the subject (as expected). Opens the drop-down text box to the first layer and... he had more corrupted.

    Someone knows something like that? Any suggestions on what to do? Color me confused now :-(

    Thank you!

    Have figured out exactly what goes wrong, will post in a different heading because it is not, in my view, a conversion problem.

  • How to restore the search bar drop-down list and the search engine icon today as it was in version FF 33?

    Some ealier time, I managed to go back to the drop down list via editing about: config and setting browser.search.showOneOffButtons to false.

    But yesterday firefox asked me to improve my search and I agreed. After that, I see ugly new tile instead of the drop-down list.

    How can I go back to find it is old menu drop-down appearance?

    "browser.search.showOneOffButtons" was a temporary pref which lasted from Firefox 34 upward through 42 of Firefox. The underlying code that have supported this preference is gone like Firefox 43.

    https://addons.Mozilla.org/en-us/Firefox/addon/classicthemerestorer/ has an option for old search (experimental) in Options of CTR > UI (1)

  • I need to rearrange the order of the 'required securities' at the top of the drop-down list bookmark.

    Hi, useful friends Firefox,.

    I need help to reorganize my combo of bookmarks to make things run in the way that I like. I am former fighter user of Firefox (and Mozilla/Composer etc. way back when). I use Firefox 42.0 on openSUSE 13.2. These two are completely up to date. I'm a fan of Firefox, which is the only browser that I use on my laptop.

    My question is about how to prefix some unwanted with "ZZZ -" titles to make sure they appear only at the bottom of the drop-down list of bookmarks, rather than at the top. The problem is that these six tracks only appear on the list box dropdown bookmarks when I press < Alt > + < B >. They do not appear in the window "library / all bookmarks" in a way I can modify them to insert the prefix. The six titles that I want to move to a more appropriate (and less prominent) space in the list are:
    View all bookmarks
    Bookmark this page
    Subscribe to this page
    To bookmark all tabs
    Bookmarks toolbar
    Download bookmark modules

    I won't be taken away entirely optional. That's why I wish they were downstairs. I just want to get them out of sight, since I was a very organized hierarchy within my bookmark system. I always use strikes, never the pointer clicks, allowing access to my favorites. Those with six in my view area when I opened my favorites to get some desired that URL seems unnecessary. By placing a prefix ZZZ - in front of them, they in alphabetical index would be at the bottom of the list, rather than at the top.

    I would like any ideas you have to help me move these six titles.

    Thank you

    Dave

    Those are the elements that appear in the list by default.
    You can try to give them a higher value of - moz-box-ordinal-group to reorder the items and move them down.
    All items have to - moz-box-ordinal-group: 1 by default.
    You can set the number to set a specific order of each of the elements.

    Add code to the file userChrome.css below default @namespace.

    @namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */
    
    #bookmarksToolbarFolderMenu,#bookmarksMenuItemsSeparator {-moz-box-ordinal-group:10}
    #bookmarksShowAll, #organizeBookmarksSeparator {-moz-box-ordinal-group:15}
    
    #menu_bookmarkThisPage,
    #subscribeToPageMenuitem,
    #menu_bookmarkAllTabs {-moz-box-ordinal-group:11}
    
    #menu_unsortedBookmarks {}
    

    The file userChrome.css (UI) customization and userContent.css (Web sites) are located in the folder of chrome in the Firefox profile folder.

  • If Google is my default search, can I go and change it if I want to do a search for GMaps; only the default is in the search drop-down list.

    If Google is my default search, can I go and change it if I want to do a search for GMaps; only the default is in the search drop-down list.
    So I have to change the default to Google Maps then back to Google to search for one.

    I have it! It's the topic: config "hiddenoneoffs" where the 3 elements of google, maps and mcafee have been included. There was no space between Google and maps. I put one in from Google Maps. She appeared in the first box-ff, but not sure about the search in the second time zone. I went back to the subject: one-offs. Safe search was shown with a space after Secure. I took out the space. Safe search arose in the 2nd single search box!
    Weird! This is contrary to how they show in the search parameters.
    Can I have messed that when Firefox has been reset all the search engines on an update, but I do not.
    Either incidentally, I tried to re-installation characteristic but the file comes down as a .dmg that I'm not familiar with and don't apparently is 8.0 to win because he couldn't open it. Thank you once again.

  • Behavior of the drop-down list

    Greetings,

    When I click on the bookmarks drop-down list opens. However, instead of appear suddenly, it begins at the top right and zoom out until it is complete. When I had too much bookmarks it was OK but now it's getting boring. I don't know if it is a feature of FireFox, but if it is I don't think. Is it possible to have just the drop just open fully?

    Thanks for your help!

    Thank you jscher! That solved. Interesting that he took and add in. Sounds like it should be an option can be set in this fine browser.

  • I lost the most views drop-down list under the search bar, it used several times in the same session, and then he just disappeared.

    The drop-down list is / was my part used of any page, use it to access to everything I need. The only other thing I noticed changed it's new green bottom-tab at the top of each page: site Web Safe/number of trackers. I can't get rid of it. Avira virus control icon is on my desktop, but the icon also suddenly appeared on the right side of the search bar. I deleted it because I have it on the desktop. I have no why he appeared suddenly. It is my 3rd session today. I had not changed anything in previous sessions, so don't know why the drop down menu has disappeared.

    Any help appreciated.

  • How to change or remove a line from a drop down list?

    I have a spreadsheet Numbers drop down box that shows the 3 lines of the text when I start typing the text in the cell. I have to enter the same text 3 times during the construction of the document. How can I remove 2 of these lines of text?

    Hi Brudduh,

    Click the cell that contains the context menu,

    Click on the brush to Format to open the Format Inspector and click cell.

    The Inspector displays the menu items in the context Menu in this cell.

    • To remove a menu item: click on the item to select. Click the button below the list.
    • To edit an item: double-click on the item to select content. Modify if needed.
    • To add an item: click on the button +. Type the content of the element.

    To use the same drop-down list in a different cell:

    • Click the cell that contains the menu to select. Copy.
    • Select the cells to the same menu. Dough.

    Kind regards

  • Why has the drop-down list of search engines under a simple list to a field of identical icons?

    Until the most recent update from the drop-down list of the available sites in the search box was easy to read and simple to use. Being able to target its research so easily and conveniently was one of the attractive features of Firefox.

    Now, I am faced with a range of more often indecipherable and in many icons that can lead to confusion of case. I hate it and I want my simple ad verbal back!

    Yes, mousing over the icons and hovering will reveal what they represent. But to have to do this each time which was a quick routine and practice irritating slow and clumsy.

    Please give us at least choose to have icons or a list. Please...

  • Drop-down list boxes &amp; menu bar drop-down lists don't no projection in 32.0

    Just upgraded to 32.0 Firefox on my laptop under Windows 7 Professional, for some unknown reason, drop-down boxes on different websites and Firefox menu bar lists drop-down would not show. When you click in the drop-down boxes, blue they just (as usual), but the list would not show. Firefox menu bar drop-down list behave the same way.

    I restarted Firefox in safe mode and this problem does not exist. I suspect it's something to do with the "Default 32.0' under 'Appearance' (as it has been disabled in safe mode). There is no 'Disable' button visible to delete this sub mode. Obviously I can not remove this in SafeMode either.

    I hope you can help as no setting change made during the upgrade and it has become unusable (so go to Google Chrome in the meantime).

    Looking forward to your reply soon.
