This template is for use when you wish to minimise information to be expanded at the user's discretion.

This usage:

{{show
|शीर्षक!
|आशय!
This information here will not show until you click the "show" button. It's then hidden by collapsing the section when you press "hide" button.}}

Yields this output:

To use this in a table: साचा:Show/Table usage

The alignment of the header text and content text can be manipulated using the parameters |headalign= and |textalign=. For example, the usage

{| class="wikitable" width=300px
|-
|
{{show
|Header!
|Content!
|headalign=center
|textalign=right}}
|-
|}

yields the output

Note that you should not put the alignment parameters in quotes (i.e., you should not use "center", but just center, or the color of the header may change. Also, while headalign=right is possible, it causes the header to overlap with the [show] button.
