How can I use an Other field with a <select> drop down?

I saw in the docs that there was gform_other_choice_value which looks like what I need, however unfortunately it looks like it only works with radio buttons.

Could I use this with a drop down with the last option being “Other” so that it would then load an field and pass the input from the user in the Other field to the backend?

You’d add an “Other” choice to the dropdown field and then add an additional field to the form under that dropdown that has conditional logic configured on it to only be visible if the user selects the “Other” choice in the dropdown field.
