Show/ hide a field based on LOV selection using Page Composer

Hi,

I need some help on building an EL Expression to show field/s based on a selected value using Page Composer.

EFFs has been created under Additional Person Info (Person EIT) to capture Super Fund details. There are 3 options to be presented and depending on the choice (existing fund, employer fund, SMSF) the information to be collected will vary.

Does anyone have experience on creating similar EL Expression? And are there any consideration/ limitations using this approach i.e. it can only support 1 selection or there is a maximum field/s this can be applied?

Appreciate if you could share a sample EL Expression to achieve this.
