Code - Display,Hide Blogger Widgets On Specific Pages

To hide (or show) widgets in particular posts or pages you can use conditional tags.

Step 1. Go to Blogger's Dashboard > Layout and name the HTML/Javascript gadgets have been already added. 

Step 2. Next thing to do is to go to Template and click on Edit HTML

Step 3. Click anywhere inside the code area and press the CTRL + F keys to open the search box

Step 4. Find the HTML of your widget by typing the widget's name in the search box - hit Enter.

Let's say that the title for one of my widgets is "Recent Posts". After searching for the widget's name, I will find a similar code in my template:

<b:widget id='HTML1' locked='false' title='Recent Posts' type='HTML'>
<b:includable id='main'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div>

<b:include name='quickedit'/>
</b:includable>
</b:widget>  

This code represents the widget/gadget that I have added in the Page Elements location (Layout).

Step 5. After you've found your widget's code, add the following conditional tags marked with red just below and above to hide the widget from specific pages or posts in Blogger. For instance, in case you want:

Note: Replace URL of the page with the address of the page in which you want the widget to appear

To show the widget only in Homepage:

<b:widget id='HTML1' locked='false' title='Recent Posts' type='HTML'>
<b:includable id='main'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<!-- only display title if it's non-empty -->
<b:if cond='data:title != ""'>
<h2 class='title'><data:title/></h2>
