filter - I don't know what the best solution is....

Hello
I'm looking on my site in French and English to add in this menu test.smilecollector.photos/fr/recherche-sur-le-site/modeles a field to filter the models.
As it's in two languages, I first thought of adding images or icons from font awesome as I can't find a common word in both languages.

The problem is that I can't find a way to make a filter... do you have an idea? what would be the best solution?

not sure to undesratnd but maybe you can use a radio image field ?
could you explain more your result wanted ?

Hello
yes - I guess it's the easier and already start in this way





which add this in the item details tab when preparing - for some, I can have 2 choices as below




My concern is now to add this field in this search:

test.smilecollector.photos/en/search/models



I imagine this is possible but I can't do it (when I guess I did by the past)

hello
1 set filter option to yes in your field
2 go yo search and filter tab and choose you wanted display (radio field)
3 go to your category and add field in filter part

Hey
I was missing the point 2
thanks a million

with pleasure
