To open accordion panel multiple tabs by default

Question

By default accordion panel opens first tab only, in case of multiple tabs. I want to open custom index tabs by default.

Answer 1

In case of 3 tabs in accordion panel, I tried following and it worked.

<p:accordionPanel multiple="true" activeIndex="1,2">

accordion panel tabs starts with index 0, so to open 2nd and 3rd tab by default use "1,2" in activeIndex attribute.
