At its simplest:

((stack|<objects>))

Alternatively, using ((stack begin)) and ((stack end)):

((stack begin))
<objects>
((stack end))

The <object> may simply be a string of wikicode for many images/templates.

((stack| <objects> | float=left/right | clear=true/false))

or

((stack begin | float=left/right | clear=true/false))

where

• float= left or right (default is right)

  This option can be used to float the stack to the left or right of the page

• clear= true or false (default is false)

  This option can be used to force the stack to the far left or right (e.g., near an infobox).

You can also explicitly list multiple arguments:

((stack| float=left/right | clear=true/false

|1=<object(s)>

|2=<object(s)>

|3=<object(s)>, etc. up to 9 parameters in the current version

))

• NB This multiple argument version does include extra vertical whitespace between each (set of) <object(s)>.

To illustrate the utility of the stack templates, consider the following situation. We would like to have two right floating images at the top of the first section of our article (here, the Lipsum section), and one left floating image at the top of the second section (here, the Lorem section). To achieve this layout, without using a stack template, we could try the following code:

=====''Lipsum''=====
[[File:Simple shapes example.png|thumb|right|Example 1a]]
[[File:Simple shapes example.png|thumb|right|Example 1b]]
... text ...

=====''Lorem''=====
[[File:Simple shapes example.png|thumb|left|Example 1c]]
... text ...

=====''Ipsum''=====
... text ...

The result of this is shown in the without stack section below. Notice how the left floating image (Example 1c) is prevented from floating above the last right floating image (Example 1b). You may need to resize the width of your browser to fully appreciate the issue. To fix this problem, we can stack the two right floating images together, using the following code:

=====''Lipsum''=====
((stack |[[File:Simple shapes example.png|thumb|right|Example 2a]] [[File:Simple shapes example.png|thumb|right|Example 2b]]))
... text ...
=====''Lorem''=====
[[File:Simple shapes example.png|thumb|left|Example 2c]]
... text ...
=====''Ipsum''=====
... text ...

The result of this is show in the with stack section below. Notice how by adding this stack template, the left floating image (Example 2c) can now float higher and is not blocked from floating higher than the top of the last right floating image (Example 2b).
