Multiple selection of tags in different levels in touch UI AEM 6.2

[umamaheswariy65]

I am using the AEM6.2 and using the tagspicker.

we can be able to select multiple tags from the one namespace at the same time if we try to select the tags from different namespace at the same time. It is not preserving the previous selections.

Content authors must be able to multiple tags from different namespace in one shot.

It is not working in OOB so I am looking for the customization, Is there any way to achieve this kind of need? Please suggest.

Thanks In Adance!!

Thanks
