I'm modelling a Filter class that stores the options for filtering a search. Some of the attributes are multiple choice.

For example, if you are filtering hotel rooms you have a Price attribute that can take these three values: Best, Average, High. You can choose many values at the same time. In an UI would be represented as a group of checkboxes.

Can this be represented in a UML class diagram?

As @robert-harvey pointed out, your requirement to select many values at the same time is strange as you can see from the model
