I want to toggle the open/closed state of the content of a paper-card element by clicking the heading of the paper-card only.
When I click inside the open content, I want the card to remain in the open state. And not toggle to the closed state.

I want to do stuff inside this content area. Some of it will involve clicking things. But when I click things, I want this paper card to remain open and not close. So I can still see this text and the other things I need to click on. But, unfortunately, with this setup, when you click on this text, the card closes and no one can read the text anymore. I'm looking for a solution that let's me open and close the card by clicking on the header "Click Me to Open" only. See what I mean by clicking on this paragraph right now. Watch it close. And not remain open like I want it.
</div>
</iron-collapse>
</paper-card>
</template>
<script>
(function(){
Polymer({
is: "x-element",
_toggleCollapse: function() {
this.$.collapse.toggle();
},
});
})();
</script>
</dom-module>
<x-element></x-element>
</body>
_toggleCollapse: function(e) {
if (!e.target.classList.contains('card-content')) {
this.$.collapse.toggle();
}
}
