Question

My question is if I can clear the styles in a specific case (in this case the accordion to place my own styles), but calling the jquery ui css to affect others if I want to show their styles.

clearStyle: true

Answer 1

Assuming your goal is to override the default styles only under certain conditions (the question is a bit cryptic), you might try adding a CSS class to the container element dynamically whenever you want them overridden. Then you can apply your styles using something like the following:

.ui-accordion.override ul {
    background-color: yellow;
}

And some sort of event to add the class:

$('#magicButton').click(function() { $('.ui-accordion').addClass('override'); });
