Dropdown Dependency on TextBox

Heya Community


I have an issue regarding a TextBox (Gallery_Level1) in a Gallery and a dropdown (or a Dropdown Dependency, if you will) where the dropdown is supposed to .

I have a tabel (Levels) with a column (Level1) and a dropdown (DD_Levels) which shows the correct possible values from Level1. The issue arrises with the TextBox not showing the values that also appear in the dropdown. In a perfect world the TextBox would include all instances of a value identical to the one given in the dropdown but im simply not there yet. Any suggestion is welcome


This is my current attempt:

Filter( Levels, Level1 = DD_Level1.Selected.Result, Level1)

Hello @Tsglavind ,


Naming a gallery "TextBox" sure made me confused for a while.


Are you trying to populate this gallery "TextBox" with the same items from the dropdown? Or do you want to append each selected item from the dropdown to the gallery "TextBox"?

Yeah sorry. The "TextBox" is a Text Label and i would like to append the chosen value of the dropdown to the Text Label

Would something like this work for you? In the "OnChange" of your dropdown:




This will append the selected value from your dropdown to your "Level1" column of your gallery. The "Reset(Self)" helps resetting the dropdown to automatically re-display its default value for user convenience.
