Feature Request: Optionsto prevent close when selecting values

[service-paradis]

Overview of the problem

Buefy version: 0.7.6
Vuejs version: 2.6.10

Description

I'm using Buefy Dropdown to select multiple values. I would love to have an option that prevent the dropdown from closing when selecting multiple values. Right now, it requires multiple click if we want to select multiple values.

Steps to reproduce

1. Click the dropdown trigger
2. Select a value (the dropdown close)
3. Click again the dropdown trigger
   4 . ...

Expected behavior

The dropdown stays open after we select (or unselect) an item. It could be an additional property.

Actual behavior

The dropdown is closed once we select a value.

You're right, I thought it after new release.
I'll add a new prop to manage it

Related to #1137. I think it could also apply to hoverable dropdown.

@yxngl @service-paradis I'm thinking to add this behaviour as default when multiple without adding a new prop

@jtommy You are right, I think it is the (most often) desired behavior when using multiple.
