Module:Basic infobox

This is a simple module that generates infoboxes.

Usage

The above field is the content of the header column at the top of the infobox.

Each row is indexed by a number and can have the following elements:

• headern: used for header rows
• labeln: optional label for data rows
• datan: data for the row (ignored for header rows; hides row when absent or empty otherwise)

Row indices do not have to be continuous.

Styles can be defined with e.g. abovestyle and labelstylen.

Example

{{#invoke:basic infobox|main
| above = [[Module:Basic infobox]]<br/>''Simple infobox generator''
| data1 = [[File:Placeholder.png|frameless|upright=1.0]]
| header2 =  
| headerstyle2 = font-size:0.5em
| label3 = Type
| data3 = Module
| label4 = Status
| data4 = Testing
| datastyle4 = background-color:orange
| header10 = Discussion page
| data11 = [[Module talk:Basic infobox]]
}}

Generates:

Type	Module
Status	Testing
