How to customize registration form and login form

Hello,
Am using the Shop & Buy template, I have 3 issues I need to deal with;
1. I can't find where I would customize or edit the registration form, or do I need to install a registration module? How do I solve the problem.

2. When I click on 'My Account' at the top right menu the pop up with title 'LOG IN or Register' opens, but there's no button or link for 'Register' on the page, How do I put the link in case the user is not already a member?

3. I will like a simple sign up form to pop up just as anyone opens the website homepage. Examples are www.jumia.com.ng or www.konga.com
I will like the same effect, how do I achieve that?

Thanks

You can edit login popup form by editing this file:
templates/gk_shop_and_buy/layouts/blocks/tools/login.php

For users that are not logged in there is a register button.

You can put register link in menu by linking to com_users registration view:

Code: Select all

index.php?option=com_users&view=registration


Thanks so much, I want to know if JED is already there or I need to install it. And in my previous question, I really want to know where (may be in module, or plug in, or component) to find registration, because I want to add some field and remove some field

Registration is a standard joomla component. We just redirect an user to it.
If you would like to modify it, please search for information on Joomla forums.
