[Feature request]conditional for more fields

[erduotong]

Is your feature request related to a problem? Please describe.

When I use it, I want to try to implement a function:
Other texts appear one by one based on the content in the multi select
However, I found that the conditional feature is not applicable to multi select

Describe the solution you'd like

Introduce the same method as select for other components when selecting and judging multi select, such as' start with ', etc

Additional context

Thank you for creating this wonderful plugin
