I want to create an field in admin panel new post entry but it should also have option of 'fill in choice' where in I can fill in a new value in that field. Is it possible anyhow?

Not possible currently, I'm afraid.
This is akin to 'free tagging', right? You might want to take a look at 'fixed tagging' that is possible and discussed here - viewtopic.php?f=8&t=8952

Perhaps that would help.

I'm not sure if you understood, it's like I have a field which has certain values in drop down form when I'm crating a blog entry from admin panel. Now I want that this field should also have an option to put in a new temporary value right from there. Say like I have a field called color which has 3 value in drop down - black, brown, red. Now I want to enter a color called blue so I should be able to fill in this value in the field without interfering with the code. I hope you get it now?

Yes, that is exactly what I had understood.
As I said, we don't have a dropdown that can be populated freeform *but* we can have one where the values are added in a separate template.

Let me explain - suppose you use a separate clonable template named colors.php and relate it with the blog template. Now when creating a blog post, the user sees a dropdown showing the titles of all pages in colors.php. So to add a new color to the list, the user can go and add a new cloned page to the colors template and that page (color) will become available in the blog dropdown.

Do you see what I'm trying to say?

Yes thank you. I will try it out.

I have seen this explained step by step somewhere on the forum, now I just can't find it Can you point me please to that topic?
Thanks.
