Hello --
You can do multiple line buttons in the collapsible steps.
Please follow these steps:
ol
liSelect certain "mobilecollapsblock" where you need to add this style. And add the "multiLineHeaderBlock" as class name. http://prntscr.com/36jojn/direct/li
liCreate new CSS. And populate it with following code:
precode
.multiLineHeaderBlock .ui-btn{
white-space: normal !important;
}/code/pre
/li
/ol
That's all.
Regards.
