Vue ignore custom component tag

In addition to the answer of thanksd, you can ignore the unknown tags by adding these tags in the ignoredElements property:

Vue.config.ignoredElements = ['gcse:search']

And you can also ignore these tags by using regex instead of using strings:

Vue.config.ignoredElements = [/gcse:*/]

This is very useful if you want to ignore more tags/components with a specific pattern. In this case, you could ignore all tags starting with "gcse"

Vue thinks that you are trying to load a Vue component named gcse:search.

In order to ignore this tag, add the v-pre directive:

<gcse:search v-pre></gcse:search>

---

Or, you could add the gcse:search tag to Vue's list of ignoredElements:

Vue.config.ignoredElements = ['gcse:search']
