Dropdown: minCharacters breaks search input

[ayastreb]

I believe this issue is caused by #1690
When minCharacters is set to 1 (by default) - it is not possible to delete the last character in search query.
When minCharacters is set to > 1 - it is not possible to enter the search query at all.

Steps

• Create a dropdown with default minCharacters
• Create a dropdown with minCharacters = 2
• Click on dropdown and start typing search query (e.g. -> "Afgan")
• Now you want to change your search query to "USA", so delete first query and start typing "USA"

Expected Result

• It should be possible to type in and change search query

Actual Result

• when minCharacters is set to 1 (by default) it is not possible to delete the last character, it always remains in the input
• when minCharacters is set to > 1 it is not possible to enter the search query at all

Version

0.68.4

@ayastreb Thanks for the excellent report 👍

I will take a look on this, seems we need more tests there after the fix.

I've made a some investigation there, as I see #1690 doesn't implemented minCharacters feature correctly. How it works in SUI (minCharacters 3):

Without input

Two characters

There characters

try for it.

fullTextSearch : true,     // default : false
minCharacters : 3        // default : 0

i hope Solve for your problems
