Current selection includes specific string

[#1]

I am trying to create a conditional expression for a button that changes its color based whether a certain entry in a field is selected. This is what it looks like:

if(loanType = 'Mortgage", rgb(32,200,53), rgb(196,0,0))

This only works if only that specific entry in the loanType field is selected. Once I select another loan type on top of Mortgage the loanType = 'Mortgage' expression is no longer true even though Mortgage is still selected. Is there an expression that I can use that remains true as long as Mortgage is selected, regardless of whether any other entries in that field are also selected?

Thanks for the help.

Try with this expression:

if(WildMatch(concat(loanType ),'*Mortgage*'), rgb(32,200,53), rgb(196,0,0))

Works great, thank you.
