Dear Community, I need your help,
I have created a lightning component and I wanted to display it in Opportunity new page. So for that, I override the "New" button on Opportunity for Mobile with a lightning component.
When a user clicks on the "New" button in salesforce one app,  After the user picks the record type. It does not going to lightning component page. 
We strongly need a lightning component page as salesforce mobile style. What can we do?
 

I want to display dependent lookup for contact based on a selected account.
I referred this link for custom lookup: http://sfdcmonkey.com/2017/07/17/re-usable-custom-lookup/
So I used this code for contact custom lookup with filter condition. When I click enter key in this custom contact lookup field, the selected account value was removed.
so I tried to disable ‘Enter’ key action on keyDown/KeyUp action. But still, it is removing.
Could you please suggest any solution for this issue?

I have created one group email "salesforcegroup@company.com" with 5 emails like (xxx@company.com, yyy@company.com, etc..)
In Salesforce, If we change the email address for a user. the verification link will receive the particular email. But if we change group email address for that particular user, the verification link is not receiving to the emails that are grouped with group email.
Is Salesforce limiting this email notification for group emails?
​Can anyone please help us to find a solution to this problem.?
