> This is a request to enhance the rendering capability of the
> HtmlSelectManyCheckbox component. Right now, this component can only render
> a single row or column of checkboxes. Often it is useful to be able to
> render an X by X grid of checkboxes. I have added the ability to acheive
> this type of rendering by introducing a new tag attribute called
> "layoutWidth" which is interpreted along with the "layout" attribute as
> follows:
> If layout=lineDirection and layoutWidth=3 and there are 13 checkboxes the
> checkboxes will be rendered as follows where each [xx] is a checkbox:
> [01] [04] [07] [10][13]
> [02] [05] [08] [11]
> [03] [06] [09] [12]
> You can see that for lineDirection layouts, the layoutWidth is interpreted as
> rows.
> If the layout=pageDirection and layoutWidth=3 and there are 13 checkboxes,
> the rendering changes to:
> [01] [02] [03]
> [04] [05] [06]
> [07] [08] [09]
> [10] [11] [12]
> [13]
> For pageDirection layouts, the layoutWidth is interpreted as columns.
> If the layoutWidth is not specified, the width can be assumed to be 1 which
> would make the component render like the original.
> I chose 13 checkboxes here to demonstrate that the rendering can handle the
> case where the number of checkboxes isn't evenly divisible by the layoutWidth.
> I am not sure if this enhancement can be made directly to the
> HtmlSelectManyCheckbox component, or if it is more appropriate to create a
> brand new component in the Tomahawk project that extends the original one. I
> will first attach patches that change the behavior of the original component,
> and wait for instructions as to whether or not these patches are appropriate.
> These patches are meant to be applied to the myfaces-api, myfaces-impl, and
> myfaces-share directories.
