Hello, the List widget might not be able to show more than one columns, and if the folding panel could not meet your requirement, then we should give it up.
I'm not sure whether the expandable Footer/ Header/ Sidebars could meet your needs, but I'll see them as a good fit:
- The Footer/ Header/ Sidebars are responsive, so they can hold a Grid widget directly (Many columns)
- The Footer/ Header/ Sidebars can be bound with a button, and clicking the button to activate the ToggleExpandCollapse service, making it "The list of rows can be opened and closed like a dropdown"
- It can overlay all widgets when opened
Hi, in that case, you can choose a responsive area in the place you want, put down a Contained Mashup widget, and put the Mashup with expandable Footer/Header/Sidebar into it. Now you could have a expandable Grid by the side of other widgets you want.
And you might try not to use too much layout in a Mashup, I assume it's better for the structure.
