I would like to display a picklist when I click on a "+" button. Do you know how to do it ?
I don't know how to use a button to do that, because it can only navigate or update a screen. Maybe I can use a hidden variable which I update with the button and use this variable in the visibility of the picklist.
If you have an idea to do it in a clean way, I'm more than interested !
You're on the right track with this, I can show you how you can hide or display fields as desired
A way to achieve this is to create another variable on the screen that stores true or false to be tied to the visibility of other objects on the screen. That way you can use the "Update current screen" automation, and just set the value of that variable to to true or false.
So for yours, here's a screen I set up to show this concept. I have a input variable for the rowlink, a button, and a variable for the visibility of the rowlink:
With the above set up, when you click on the button in the app, the visibility will update from false to true, and you will see your picklist to select from.
Would it be possible to apply the same concept in a situation when instead of button to select (as above), i can setup a picklist (Picklist-1)and then selection of any value in that picklist drives the visibility of subsequent picklist (Picklist-2) ?
And for the data cell for the items, I've set it up as a filtered rowlink to the items table (child rowlink), to only show the items related that space:
The filter in my example being: =FILTER(Items,"Items[Space]=%",$[SpaceSelector])
