There is no way to place a widget such as a DropDown in a table cell. You would have to place it somewhere outside the table.

@zhouruisong

the way you can implement this the quickest/easiest would probably be Pages widget, with the table on the back layer, and then when a user hits the cell/shortcut to use this dropdown, stick it in a modal dialog and put it on the front layer of the pages widget. this has the added benefit of giving you lots of room/space for other help/buttons/widgets beyond the dropdown.

if you really want to mimic a dropdown's home/position being from/in/with a table's cell, there's a method on table cell's GetLastPosition that you can call to find the coord's to then position a box/widget/panel/modal close to your cell.

your issue's title gave me an instantaneous reaction of FUCK THAT when breezing headings. anything in a cell, is restricted to the cell's size/position, as well the cell is restricted to the table's size/position/scroll. , and table cell's are text only to begin with, without any logic to render primitives inside themselves

I would however try and think how best to handle things you want to do without mimicing a desktop GUI you may think people are accustomed to... console users are there for the speed/consistency/scriptability/predictability of their interface, and sometimes lacking a mouse (servers/ssh). so terminal apps aren't going to usually be seen as useful if it is another poinit and click adventure they could have kept open in a chrome tab.

now, i attach this gif to show that with some creative uses/styling of the basic widgets already in tview, you can create an engaging UI/UX without trying to duplicate a desktop GUI in a tty world.

you can see how overlays/dialogs/panels that pop over, slide in, dock/post up, can give your user's their widget/option/utility/functionality you're providing.

but this was a toy project so some of the ui/ux is excessive lol
