This is essentially a Pop-Up. Doing a Google search 'PowerApps PopUp' will find heaps of examples but here's one from @mdevaney that is quite good:
https://www.matthewdevaney.com/how-to-create-a-pop-up-menu-in-power-apps/
The basics are
- add a rectangle, set it's fill and transparency to suit your needs
- on top of that add the rest of your controls ie Labels / Buttons / Icons / etc
- make sure all of these controls sit above the existing controls on your screen (TIP: use Ctrl+[ or Ctrl-] to move selected controls up and down)
- make sure you include a 'X' (cancel) icon somewhere
- Group all of these PopUp controls into a Group
- Set the Visibility property of this Group to some variable name eg showPopUp
- On the OnSelect of your '+' icon, set this variable to true, ie
UpdateContxt({ showPopUp: true })
- On the OnSelect of your cancel icon, add this code (TIP: you can also add this code to the OnSelect of your rectangle if you like?)
UpdateContxt({ showPopUp: false })
Then, get creative 🙂
