Hi,
I want to add a custom field which will be a drop down list, but I want to be able to "treat" the values some times as number ( for aggregations, numerical comparisons, etc.) and sometimes as text (especially as a legend for the values' meaning). attached is an example.
Is that doable OOTB? or do I need a plugin for that? if so can you point to some examples?
my question is abet complex, I hope I explained it well, any assistance will be useful 
Thanks in advanced,
Keren
