Disable dropup feature using Bootstrap Select

问题

I'm using Bootstrap Select to style some select fields inside an accordion. Bootstrap select has a feature where it will make your dropdown dropup if it is near the bottom of the screen.

In this case I do not want it to drop up but I can't find where to disable this.

回答1:

Options can be passed via JavaScript or data attributes:

$('.selectpicker').selectpicker({
    dropupAuto: false
});

or

<select class="selectpicker" data-dropup-auto="false">
    <option>Mustard</option>
    <option>Ketchup</option>
    <option>Relish</option>
</select>

You can also set this globally:

$.fn.selectpicker.Constructor.DEFAULTS.dropupAuto = false;

回答2:

This setting can be changed in the bootstrap-select.js file by editing the dropupAuto option to:

dropupAuto: false,

You can use this to disable the picker. $('.selectpicker').prop('disabled', true);
