Is it advisable to use jquery library in lightning component?Please provide reasons too.

How do i convert a text file to csv file and then upload it into salesforce?

Hi,

I am trying to set the default value of "RelatedTo" field on activity to a custom object. In classic we can simply use URL hacking & custom button to set it. But in lightning i haven't figured out any solution.By default Related To has defaulted to Accounts...Also I know there is an Idea Pending with salesforce, But i was wondering what is current workaround.



So if anyone know ANY way to set "Related TO" field on Activity please let me know. Is visualforce page to replicate the whole Activity section ..the only option?

Thanks for your time:)
