Tab display - validations across different subtabs

RE: Tab display - validations across different subtabs

Hi, I need help on something

I have a button array layout, with each click it will add a tab with fields to enter. Each tab has same set of fields with validate button. If data enter is correct it will validate and displays a new section below to add further information.

Below is the case:

I need user to validate everytime they change the initial values they entered in the tab and when they update the value after validating 1st time, new section below which is added before should be hidden until validation is done again. This should be done for all the tabs user adds.

Thank you.

Hello tomislavf0001

I think what Stefan said is correct. Have some checks on your variable and highlight the tab that contains the missing data. That would be better option if you are having nested tabs.

Appian will only validate the visible input fields. But, any validation is always done on the data in variables and rule inputs. So, you can easily highlight tabs and sub tabs when some data is missing or wrong.

Yes it is possible to validate the data within the tabs if we use validate:true() in the button component .
Suppose lets take a milestone field and you have next button having validate as true in the component so when you click on next it will validate the components only visible in that tab not all and validation will be shown and you can't proceed to next tab

Refer for milestone patterns in the following link
