Is it possible to open a selectbox with JavaScript? Or with jQuery?

In short: no, it's not possible. Long answer, see How do you open a select box with JavaScript?.

If you want to "open" a selectbox, this is impossible - see Stack Overflow question Click trigger on select box doesn't work in jQuery for more information.

If you want to select a value, you should use .val().

Can't be done, you can use .trigger('focus') but it will not open the drop down.
