Expanding Gallery - How to only have one expand and not all?

(0) ShareShare
ReportReport
Posted on by Purrple 30

I am setting up an expanding gallery as a navigation for my page.

There is one gallery (gal_CFTNav) which groups the items by a common category. (Groupby('CFT List', "CFTGroup", "DATA").

There is a button that indicates the name of CFTGroup

 

There is a nested gallery (gal_CFTData) which lists the DATA

 

I have set the OnSelect for the button to UpdateContext({NavVisible:true})

 

This expands all of gal_CFTData but I would prefer to only expand the navigation based on the CFTGroup button that was pressed.

What am I missing?

    You are missing that you are setting a variable to true or false.  That variable is not record specific, it is just a variable.  So all of your rows will respond to it.

    Instead make your variable record specific.

    Ex.  UpdateContext({NavVisible: ThisItem.CFTGroup})

    Then have your visible or other property based on that.

    Ex on a Visible property:  ThisItem.CFTGroup = NavVisible

     

    I hope this is helpful for you.

    This did not work exactly like this for me - ThisItem.CFTGroup could not be assessed, but using this logic I updated it to ThisItem.IsSelected and got the desired result.

    Thank you once again for your help!

    Yep, that will work too.  It will not be as accurate, but it would work fine.
