I am using lightning:tabSet and lightning:tab to display 3 user forms shown in the 3 tabs.
I would like the user to fill out the form on the first tab before he clicks on other tabs. How should I gray out other tabs until the first tab is clicked.
I can use "v.selectedTabId" to set a tab but without graying out this might confuse the user. I would like to gray out a tab to clearly indicate that it cannot be clickable.
