Perfect, it works.
Thank you.

Hello,
I need your help please.

How can I remove all options from a combobox?

I have a combobox and load the data from a remote URL.
Thats all works very well.
But I need a function, which I can remove all loaded options from the combobox.
I have already test the 'clear' and 'reset' methods, but with this methods only the value was remove. The options are still there.
