  Enable AI AnimationTo do this you don’t need a lot. I’ve hinted at this kind of stuff before with my [Lookup Select Attribute](https://jace.pro/post/2017-10-28-lookup-select-attributes/) post. Here I’ll spell it out.

Make `category` variable with the following bits

Type: Lookup select box
- Include none: true
- Table: `sys_choice`
- Reference Qualifier: `name=incident^element=category^language=en^inactive=false^ORDERBYsequence`

- Make `subcategory` variable with the following bits

Type: Lookup select box
- Include none: true
- Table: `sys_choice`
- Reference Qualifer: `javascript: 'name=incident^element=subcategory^language=en^inactive=false^dependent_value=' + current.variables.category`
(note the dependent value column in your query)
- Attributes: `ref_qual_elements=category`
