how I work when the <select name "test[]"> is an array

[JuanJoseVegaT]

I am implementing the multiselect in a filter form that reloads a dataTable with the selected options when the form is submitted the function that reloads the dataTable does a .serialize() of the form to reload the page with the corresponding information.

when I choose only one option in the select it works perfect but when I choose several options from the same select it only takes the first one and I see that the path of the .serialize() is incomplete only taking the first value.
