Hello,

I have a grid with a menupop to select the hidden/visible columns. When I hide a column and then I click on the header to execute the sorting method, all the columns become visible. Is there any option to keep this columns hidden?

My code is something like this:

<grid id="GRIDCenso" mold="paging" pagingPosition="bottom" autopaging="true"
      span="false" sizedByContent="true" pageSize="10" width="100%" 
      xmlns:a="client/attribute" a:data-scrollable="false"
      model="@load(vm.beans)">
    <custom-attributes org.zkoss.zul.grid.autohidePaging="false"/>
    <custom-attributes org.zkoss.zul.image.preload="true"/>
    <columns menupopup="auto-keep" sizable="true">
        <column  width="40px" sclass="hiddenSelector"/>
        <column id="CLCama" sort="auto(cama)" hflex="min"/>
    </columns>

Thank you!

there's no such feature available out of the box. When using MVVM you store the UI state anyway in the view model e.g. keep the column-visibilities in a list of booleans, or a map (whatever you prefer), Or just keep a whole list of columnInfo objects containing getters for column information (label, visbilitiy, sortability ...)

You can then control the visibility using a @load-binding.

https://zkfiddle.org/sample/1n6hjff/2-keep-column-visiblity

The column menu can be customized (see fiddle above) at client side or a custom menu can be defined.

Then when sorting is triggered you can trigger the @load binding via notifyChange or as I do in the example using a conditional @load(..., after='sort') binding
