How to remove the class - form-inline

[samprati]

I am stuck in a situation where my form gets messed up due to form-inline class.

I installed a plugin vue-query-builder and used it in my form. i added some input fields to my form and the form layout is not as per my requirement.

Upon looking into the console elements, i saw there is a div which has the class form-inline. Upon deleting that class, the form looks good.

I tried overwrite the form-inline function by adding custom css, still cannot get to remove the class

.form-inline {
    display: contents !important;
    flex-flow: unset !important;
    align-items: unset !important;
  }
