Creating a field that can hold over 100+ values

[Yaharin]

Hello, 
I have a Tasks project and I would like to tag each ticket with a specific value (in this case - clients names). I have a list of over 100+ clients names. 
which field can be compatible for this criterion? 

Thank you.

You can create a static dropdown list with every customer you have, 

Settings -> Issues -> Custom fields, search for "customer", click on the 3 dots on the right, select "context and default values and you can add them there
