[grid] Add "hidable" property to column

[denis-anisimov]

vaadin-grid-column component has an attribute hidden which allows to show/hide the column.

But there is no way to mark column as hidable. Such column should allow to hide the column for the user (or disable that functionality).

See the Java API method for Grid column in FW8:
https://github.com/vaadin/framework/blob/master/server/src/main/java/com/vaadin/ui/Grid.java#L1835

Please add support for this.

Isn’t it enough to add a hidable attribute on the element to track which columns are hidable? I don’t see the need to have any special support for this in the component implementation. Or is it necessary to receive a changed event for this?

[denis-anisimov]

I don't know.........

Is hidable attribute supported ?

As I understand the hidable property/attribute means that there is a UI control available for the column on the client side which allows to hide the column (though I don't know how it should be set visible back after hiding).
I don't remember the Grid behavior on FW8 regarding this feature.
Sorry, can't find any FW8 component demo on our website.....

Oh, so this is about having the UI as well. I was just thinking that you needed to keep track of the columns which the user can hide/show.

We need a UI design for this.

Also, after this gets implemented, we can close vaadin/vaadin-grid#819

[denis-anisimov]

Sure

[scrmtrey91]

will this be implemented in vaadin 14:

addColumnVisibilityChangeListener

????

[scrmtrey91]

and also this :

• setHidable on column when adding column

Renamed this, and keeping it open for the hidability property, and keeping vaadin/web-components#1569 for the UI for toggling columns.
