As an Administrator, WordPress allows you to use the User Roles section to set the permissions and access of the user . You can access it from your Dashboard by clicking on Users > User Roles: 
In the User Roles section, you can create Role and determine which admin pages can be viewed and modified by each Role . 
Note that you must know which pages can be accessed or modified with the Access and Modify permissions. 
You have five pre-defined User Roles in your default WordPress installation – Administrator and Editor and Author and Contributor and Subscriber. While the Administrator Role has all the permissions . You can not delete Administrator. Click on the Action button for one of the User Roles to see the permission fields.
The Edit User Roles section gives you one field – Permission, the Administrator User Roles has all the permissions. However.

Hide This provides a <code>[hide]</code> shortcode that lets you hide some parts of the content from your posts and pages. You can easily manage inclusions and exclusions for hidden content in three levels: absolute, groups and capabilities, and specific user.
Maybe some part of your post should not be published yet? Or maybe you want to show some specific parts of your content to a certain group or users, let’s say your logged in users or your clients? This plugin may be the solution you need.
It’s very important to note that the content wrapped within the shortcode won’t even be printed as HTML. It will be really, really hidden. There are a lot of great plugins that hide the content via CSS and Javascript, but this is not the case. If you want your content to not be visible, but still printed as HTML, you should try one of those.
Basic usage:
<pre><code>[hide]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
This example will hide that content for all the site visitors. But you can be more specific by using attributes.
Accepted attributes:
<ul>
<li>for: (optional) your rules to hide content. You can use absolute rules (<code>all</code>, <code>none</code>, <code>[!]logged</code>), rules by roles and capabilities (<code>[!]{role}</code>, <code>[!]{role}:[!]{capability}</code>, <code>:[!]{capability}</code>), and rules by specific user (<code>userid:[!]{ID}</code>, <code>useremail:[!]{email}</code>, <code>username:[!]{username}</code>).</li>
<li>exclude: (optional) your rules to show the hidden content to some specific visitor/s. As in for, you can use absolute rules (<code>all</code>, <code>none</code>, <code>[!]logged</code>), rules by roles and capabilities (<code>[!]{role}</code>, <code>[!]{role}:[!]{capability}</code>, <code>:[!]{capability}</code>), and rules by specific user (<code>userid:[!]{ID}</code>, <code>useremail:[!]{email}</code>, <code>username:[!]{username}</code>).</li>
<li>test: (optional) for debugging purposes. The kind of output you expect. Accepts <code>content</code> and <code>empty</code>. Use it wisely, because it prints a message with the result of the test.</li>
</ul>
Some useful examples:
Hide your content to all visitors:
<pre><code>[hide]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content to all visitors, except for a specific user:
<pre><code>[hide for="all" exclude="username:foo"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content to all non-logged visitors:
<pre><code>[hide for="!logged"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content to all logged in visitors:
<pre><code>[hide for="logged"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content to all logged in visitors, except for a specific user:
<pre><code>[hide for="logged" exclude="username:foo"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for some specific role:
<pre><code>[hide for="contributor"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for two specific roles:
<pre><code>[hide for="editor, contributor"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for all visitors except for a specific role:
<pre><code>[hide for="!administrator"]Lorem ipsum dolor sit amet.[/hide]
[hide for="all" exclude="administrator"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for all visitors except for two specific roles:
<pre><code>[hide for="!administrator, !editor"]Lorem ipsum dolor sit amet.[/hide]
[hide for="all" exclude="administrator, editor"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for users with a specific role and a specific capability:
<pre><code>[hide for="some_role:do_a_barrel_roll"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for users with a specific role, not having a specific capability:
<pre><code>[hide for="some_role:!do_a_barrel_roll"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for users with a specific capability:
<pre><code>[hide for=":do_a_barrel_roll"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for a specific user by user name:
<pre><code>[hide for="username:foo"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for a specific user by user ID:
<pre><code>[hide for="userid:42"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for a specific user by user email:
<pre><code>[hide for="useremail:foo@mail.com"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
Hide your content for everyone except for a specific user by user name:
<pre><code>[hide for="username:!foo"]Lorem ipsum dolor sit amet.[/hide]
</code></pre>
You should get the idea by now. Notice how you can use <code>!</code> to deny values such as login status, roles, capabilities and user values.
