Customising the display of macro parameters in the editor placeholder

It is possible to customise the way the editor displays macro parameters in the macro placeholder.

By default as many parameters as can fit will be displayed in the placeholder, as shown here:

You can control which parameters you want to display here, to ensure the most relevant information is visible to the author.

For example, the Confluence Warning macro has two parameters, title and icon. We consider title to be the most interesting parameter, so the macro is configured as follows:

1
2
<xhtml-macro name='warning' class='com.atlassian.confluence.extra.information.xhtml.WarningMacro' key='xhtml-warning'>
    <description key="com.atlassian.confluence.extra.information.warning.desc"/>
    <device-type>mobile</device-type>
    <category name="formatting"/>
    <parameters>
        <parameter name="title" type="string">
            <option key="showNameInPlaceholder" value="false" />
            <option key="showValueInPlaceholder" value="true" />
        </parameter>
        <parameter name="icon" type="boolean" default="true"/>
    </parameters>
</xhtml-macro> 

The 'showNameInPlaceholder' option is set to false which means the name of the parameter (title) will not be displayed. In addition the presence of these options on any of the macro parameters means that any other parameters without explicit options set will not be displayed.

Let's assume an author adds the Warning macro to a page, and gives it a title of 'The title of the warning'. The above configuration leads to a placeholder as shown here:

Parameter details

If none of the parameters in a macro include any of the above options, then the default behaviour is to show all the parameters that fit in the placeholder: full title and value.

If one or more parameters has either option set, then all parameters that do not include the options will default to false (that is, they will not be shown).
