Including theme snippets in diazo

Hi all,

I have the following use case:

My diazo theme will include one of more theme html files depending on the part of the site which is visited. I am able to create a rule which conditionally loads a html template.

I want to include a common html fragment mega-menu.html in any of the templates rather than duplicating the html.

|          |--services.html
|          |--blog.html
|          |--mega-menu.html

If I replace the nav element from one of the template with my mega-menu nav e.g. like this:

<replace css:theme="nav" css:content="nav" href="++theme++my.theme/html/mega-menu.html" />

the fragment is included but I am unable to apply any further customizations.

How can this be done?

It will take some slight refactoring but you can get what you want done with collective.themefragments.

Hi David,

Cheers for the link! I looked at that, and the jbot variant, but decided against it because it adds another layer of complexity. Preferably, a designer who can create a bootstrap based theme but does not necessarily know Plone or PageTemplates should be able to maintain/extend the current theme.

While typing, I revisited this stackoverflow question

This seems to do what I want, but only if used in the top-level rules element

<replace css:theme="nav">
    <xsl:call-template name="nav-replacement" />

<xsl:template name="nav-replacement" match="nav">
    <xsl:element name="nav">
        <xsl:apply-templates select="document('++my.theme/html/mega-menu.html',$diazo-base-document)/html/body/div/nav/node() "/>
<drop css:content="nav .navbar-toggle" />

I'll see how far I get if I attempt my replace again in the root rules...

Edit: the original replace rule does not work in the top-level root element.

with this simplified version, dropping the element works but redefining does not...

<replace css:theme="nav">
    <xsl:apply-templates select="document('++my.theme/html/mega-menu.html',$diazo-base-document)/html/body/div/node() "/>
<replace css:content="nav .navbar-brand" css:content="#portal-logo"/>
