Taxonomy and Stash - primary navigation

gistfile1.txt

In the viewModel:

{exp:stash:set name="nav_main" parse_tags="yes" save="yes" refresh="60" replace="no" scope="site"}
{exp:taxonomy:nav tree_id="1" depth="1" ul_css_id="my-id"}
    <a href="{node_url}"{stash:nocache}{if "{exp:stash:get name='segment_1' type='global'}" == "{/stash:nocache}{node_url}{stash:nocache}"} class="active"{/if}{/stash:nocache}>{node_title}</a>
{/exp:taxonomy:nav} 
{/exp:stash:set}

(I'm assuming Taxonomy {node_url} is something like 'my_page' NOT 'www.mysite/my_page', so that we can compae it to {segment_1}- if it produces something else adjust the conditional above accordingly)

In the view:

{exp:stash:get name="nav_main" scope="site"}
