Tag dependencies is still in beta, thus it is necessary to use this work-around:
- {{url}} matches RegEx .* AND event=gtm.dom
Start TagA -> Fires on dom ready (gtm.dom)
-> sends event “header-jquery-loaded” to the dataLayer
dataLayer.push({“event”: “jquery_loaded”}); // CustomHTML
- Then TagB fires on “donewith_tag_a”
-> sends event “donewith_tag_b” to the dataLayer
dataLayer.push({“event”: “donewith_tag_b”}); // CustomHTML
- Then TagC fires on “donewith_tag_b”
-> sends event “donewith_tag_c” to the dataLayer
dataLayer.push({“event”: “donewith_tag_c”}); // CustomHTML

The tag priorities feature was recently added in advanced setting for onclick events, but this can not be used for AJAX based trigger tracking, then load the next tab events, this requires tag dependencies.
| Priority | Name | Example |
| 0 (default) | 1th group of tags | header_jquery_loaded |
| -1 | 2th group of tags | donewith_tag_b |
| -2 | 3th group of tags | donewith_tag_c |
