How do I remove a item from list picker?

I am trying to make it so that when I click on my remove glass size list picker, it shows the options that are available, then I need it so that when you click on one of the option it comes up saying would you like to remove yes or no. I am stuck on trying to remove items from the list, I think I will be able to do the rest of it with the yes or no part etc.
Below is my code. Thanks in advance.

Change to global glass_size.

Thank you, that made it kind of work. But the initial 3 in the first list dont all appear and when one is removed it sometimes adds one of the 3 that were pre set in the list back into the list picker for some reason. Any idea on how to fix this?

Because you are not storing the list (glass_size) in TinyDB, initially.
Do you want them to be added to the list every time the app is launched?

Can you share some DoIt results. Your statement is unclear. (to me)

Try this


When using Notifiers for confirmation, it is important to immediately rename the new Notifier component to mention the question it asks, like

  • Do you want cream in your coffee? (Yes/No)
  • Are you sure you want to launch the Nuclear Missiles? (Yes/No)

It is also a good idea to use more specific text in the expected response, like

  • Cream/Black
  • Launch/Recall

to avoid last instant confusion.

Right thank you for this, it works well. But I needed it on a seperate list picker, and when I changed it over to list picker 2 and I try to remove an Item it says "Remove list item: Attempt to remove 0 of this list ["Can (330ml)", "Whiskey Tumbler (250ml)", "100"] The minimum valid item number is 1.
Any idea on how to fix this. Thanks in advance.

Post a screenshot of your blocks

Thank you

Change from ListPicker1.Elements to ListPicker2.Elements and from ListPicker1.SelectionIndex to ListPicker2.SelectionIndex

Yes I should have seen that, thank you works perfectly now.
