Expandable List

How can i create expandable list view with active content in list’s item? its should look like android expandablelistview if possible and what kinds native filter can i use for him.
as suitable option for a drop-down table row and similar

I can suggest three solutions:

  • use the stylized treetable
  • use a datatable with subrows or subview (both pro-only)
  • use the stylized tree. There was a topic with a similar solution. Filtering, active content and html buttons will work as expected.

list item not support nested data?

If you have a relative small number of items - you can use a datalayout with accordion inside

For big number of items, check subview feature of datatable

You can use a single column datatable without header, if you wish to have a look similar to the list.
