How do I change the input type of an exposed filter in a view? I have a view which lists products. I created an exposed filter based on price criteria.

The exposed filter shows a text input where you can type an integer number to get the products filtered. What I need is to replace the text input with a select list showing values such as 50000, 100000, 1500000, 200000.

I have the Better Exposed Filters module, and the Views PHP module enabled.
Edit View >> Configure filter criterion >> Select grouped filter (instead of the default, single filter) >> Set-up your options. That's it! you now have dropdown filters of free filled node field.
