Set width of container to fit text area




I have the following dropdown:

Which opens to this:

On selection of one of the options, I have the dropdown now reflecting the selection, however I want the container to expand to fit the text string and icon to move to the right also to arrive at this:

I have tried setting the size of the container using the following function. However it doesn’t seem to work.

Any help would be appreciated.
Thank you


You’re on the right track. The reason your function didn’t work is because you used “text on widget” instead of just “widget” when you set your local variable.

Depending on how you build your list, you can use the size of the widget containing the text as the variable instead of hard coding the widths of each, individual option: Resize_Dropdown.rp (62.0 KB)


So I’ve tried to reconstruct the module, I’m getting closer to the desired behaviour thanks to your input, however I am still facing a couple of nitty gritty details.

  1. The flyout closes when I focus out of the area with the mouse, it should stay open
  2. The flyout doesn’t close if I tap on the dropdown again
  3. The dropdown stays in an active (blue) state even if no selection has been made from the options
  4. The chevron does not rotate

I have multiple of these dropdowns on a horizontal plane. Do you know how I could go about utilising the resized dropdown to push the rest of them to the right?

As far as the drop list closing on mouse out, it’s a built-in behavior for the “treat as flyout” option when showing a widget. If you want it to stay visible on mouse out, just set the option to “none”. You’ll have to use some other trigger to hide the list. The easiest way is to use “Page Click” to hide the list if the cursor isn’t over it.

You can tackle the other three issues a few different ways, but it basically breaks down to needing a trigger to reset everything back. Since the dropdown button is a dynamic panel, setting it to “selected,” also sets all the widgets inside of it to “selected” as well. (The same is true for “groups”.) I set the chevron icon to rotate 180° whenever it was selected or unselected.

The trigger I used to “reset” everything was to have the list widget set the dropdown button to “Unselected” whenever it became hidden. That would set the button back to its default styling and rotate the chevron. Having the button to show or hide (toggle) the list onClick will set everything back to default.

You can dynamically move the row of dropdowns by setting up a kind of “cascading trigger.”

Whenever the first dropdown is resized, have it move the second one to its right plus whatever padding you want:

On Resize, move "second dropdown" to [[This.right + 8]]

Then, on the second dropdown, set it to move the third one whenever it is moved, and so on.

Ok, we’re getting very close. I think I may have mis-communicated point 3. So, the intended behaviour is the following:

  • Default state = grey + default placeholder + arrow down

  • If flyout opened, then it should have active state = blue + placeholder + arrow up

  • If flyout opened and closed without selection = should stay in default state

  • If option selected from dropdown, then it should have selected state = blue + placeholder change + arrow down

  • If selection made, then flyout opened and closed again = selected state (blue + placeholder change)

Basically, would it be possible to somehow fire the mouse style effects if an option is selected from the flyout?


Sure. You just can’t use chevron’s “selected”/“unselected” interactions to set its rotation anymore. You could set it up where clicking the dropdown rotates the chevron to the “up” position and have the list rotate it back when it hides.

If I understand you correctly, another way of describing what you want is to say, “The dropdown has the selected style only when open or is not the default option.” If that is the case, then when the list becomes hidden, it checks to see if the text on the dropdown says “default”. If true, then set the dropdown to the “unselected” state.
