[jmurugan-fzj]

Is your feature request related to a problem? Please describe.
GUI adaptations for the data-hierarchy editor. A better GUI with tab-view for the metadata groups and other modifications too.

Describe the solution you'd like

1. Data type row changes

   • For "Data type" row requires a combo-box (listing all doc type labels), Add, Edit and Delete buttons

     • Add functionality

       • Should show the exisiting form with entries for the following
         • Data type (LineEdit)
         • Title (LineEdit)
         • IRI (LineEdit)
         • Shortcut key combination (LineEdit)
         • Icon (LineEdit or drop-down for the list of icons?)
       • Remove "is structural type" checkbox from the form

     • Edit function

       • Edit form should be similar to Add, except for the data type entry which should be read only.
       • Also for "structure level type", icon and shortcut entries should be read only items

     • Delete function

       • Similar as before, should be disabled for structural items

     • Structure level 0 & Structure level 1 are only supported, delete functionality should be disabled for both. Edit form for "structure level type" should display icon and shortcut as read only items

2. Changes for metadata group

   • A tab-view to be implemented with each tab referring to individual metadata group. Add button in the tab view should add a new group. The body of the tab-view should display the same table as before for respective groups. Delete icon should be present in the tab itself for each group. Ideally tab view should be scroll-able.

3. Add attachments table

   • Keep a dedicated tab for the attachment table in the above tab-view and body should be same as before.
