Select Filter query doesn't work option 'Show All'

[Ivcast20]

I'm doing a datatable with products table and this table has a foreign key to categories, but when I make the filter I doesn't show me the All option
this is my code

I tried to add show all in the options

but I got this error

I think i have the answer, but i don't know i there's other way of doing it.
All I had to do was this.

@Ivcast20 - no, you've done that correctly!

I have however opened a Pull Request to add in a "setFirstOption()" function for the Select Filter. Not sure if/when @rappasoft will merge this, I've been quite active in creating pull requests lately, so he's got quite a few to look at!
You are of course welcome to extend the SelectFilter class, and implement the functionality now (or amend the vendor files - at your own risk), should you so wish!
