Conclusion: It works! Congratulations! Adding new list will add new to dropdown menu and deleting a list will remove it from the list.

Why no support:
It's too complicated. How would you select what's in the dropdown? That pretty much covers the cons.

Workaround:
The workaround is quite simple.

1. Create a new project. Add some lists, and add a block with an input.

2. Add the list's name as the first item of the list. Repeat process for each list.

3. Download the project to your computer!

4. Save it as a .zip. Save as all files.

5. Extract files from the .zip. Do not delete it.

6. Open the folder. You will see a text file called project.json. It has pretty much everything. And text pops up.

7. Keep scrolling until you see the ProcDef command. It should say the custom block's name.

8. See those % things? That is the type. change it to a %m.list. It changes input type to list.

9. Don't forget to save it!

10. Transfer it to the .zip file! Delete the text file in the .zip folder, and drag text file from Extracted folder to .zip file.

11. Import the .zip file into the Scratch editor.

12. The .zip file is in Custom Files. Change file to All Files. Double click it.

13. Congratulations! You did it!

define add [object ▾] to inventory
if <(object ▾) = [( ͡° ͜ʖ ͡°)]> then
 say [( ͡° ͜ʖ ͡°)]
else
 add (object ▾) to [inventory v]
end
when gf clicked
add [lenny v] to inventory

My suggestion is simple: that when you create your own block, along with boolean, string and number input, you were allowed to do a dropdown list like this:

define move [direcion]
if <(direction)=[up]>
point in direction (0 v)
move (10) steps
end
if <(direction)=[down]>
point in direction (180 v)
move (10) steps
end
when green flag clicked
move [down v]

I would find this very useful (though admittedly my example wasn't very useful)
Any suggestions, improvements or just support?

%d They will be added in future!

The Unicode white down-pointing small triangle (U-25BF) could be used to indicate the dropdown variable.

define move [direction ▿]
if <(direction ▿)=[up]>
point in direction (0 v)
end
if <(direction ▿)=[down]>
point in direction (180 v)
end
move (10) steps

when green flag clicked
move [up v]
move [down v]

Makes sense… the only thing is that although the input method for a dropdown input would be different it would behave pretty much like a string, so maybe it doesn't need an arrow symbol.. Although if this makes it easier to understand for beginners then I guess so…

True.

When I saw your example it helped me to think about how this could be done.

define move [direction]

gave me an expectation of

move [ ] ::custom

//or

move () ::custom

but not

move [down v] ::custom

as the block it would define.

So a new solution occurs to me.

define move [direction] ▾ 






move [down v] ::custom

ScratchBlocks doesn't support v for a drop-down menu for the define block.

So the v is Unicode black down-pointing small triangle (U+25BE).

Clicking on the ▾ in the define block (where it's white) would show a menu of lists.

Select a list and the items of the list become the options in the drop-down menu in the custom block.

A blank list item would produce a non-selectable separator line (the black bar).

A list item of the form (number) string would produce menu options like in the direction block.

Thus, each drop-down menu in a custom block would be defined by a Scratch list.

Easy-peasy

what if you want a list of list names?

define move [direction]
if <(direction)=[up]> :: control
point in direction (0 v)
move (10) steps
end
if <(direction)=[down]> :: control
point in direction (180 v)
move (10) steps
end
when green flag clicked
move [down]

No support, too specific as this:

define(custom reporter::custom)
...

set lang to [French v]::custom
