Mostafa,

I don't think there is way to skip the loop, alternatively what u can do is, keep "if condition" to do your operation if particular condition matches, for eg:

to print div if your boolean value is true and skip if false, you can use:

<t t-foreach="<list_of_obj>" t-as="obj">

     <t t-if="obj.<bool_field>" ><!-- checking if field is True *-->

         <div>  Created when field is True</div>

     </t>

     <!-- No div will be created in 'false' case -->

</t>

Hope it helps!!
