When enabling filter_mode in select the space is swallowed

[sagoez]

When trying to type into the filter I can't write a space separate word. The space is swallowed, i.e:

Key::Char(' ') => {                                                                                                                                                                                            
      self.input.delete_left();                                                                                                                                                                                  
      None                                                                                                                                                                                                       
  }  

This could be configurable, no?

@sagoez yeah, it could be configurable, but the problem is that the space bar switches the selection in the list. So maybe enabling spaces in the filter line should change the key which flips the checkboxes

[sagoez]

Maybe, that's a sound decision to me. I can help with that if you want me to.

@sagoez The main challenge is getting the UX right.

Select (radio buttons):
We can allow spaces in the search/filter input without issues. In this mode, users navigate with arrow keys, and items are effectively auto-selected, so the space bar isn’t doing anything important anyway.

Multiselect (checkboxes):
This is trickier because the space bar is used to toggle items.

One workable approach:

• As soon as the user starts typing (any character), we clear the current selection (so the cursor isn’t on any item).
• While no item is selected, space goes into the input as a normal character.
• If the user moves with arrow keys, selection becomes active again, and space toggles items instead of going into the input.
• To type spaces again, the user either goes back to the input or types more characters, which clears the selection again.
