I am really sorry but our support does not include customizations. I would suggest that you take a look at the codes in /components/com_easyblog/views/latest/view.html.php to look at how the data is being retrieved.

I do not need you to do customisations.
I understand that its not your job, but help in pointing out the right path would be great

like if you see the edit.php in my given easyblog plugin

<select id="wk-category" class="uk-form-width-large" ng-model="content.data['category']" multiple>
<option value="0">{{'All' | trans}}</option>
<?php foreach (\JHtml::_('category.options', 'com_content') as $option) : ?>
<option value="<?php echo $option->value ?>"><?php echo $option->text ?></option>
<?php endforeach ?>
</select>

Where it pulls joomla's content component's categories, how can I pull categories/bloggers etc from easyblog

is there any similar format like easyblog.categories something?

Also I have posted same ticket to yootheme
https://yootheme.com/support/question/98867

where I can get help from their part of technical aspect.

Little push from you and little push from them will do the Job

Firstly, reading your code takes time and we are not familiar with Yootheme / Widgetkit either. It is ideal that you look at our existing codes in the views folder so that you can understand how we retrieve the data.

For categories, take a look at /components/com_easyblog/views/categories/view.html.php

Ok..

Can we get list of Categories using JHTML :: ???

No you can't. You need to refer to the codes in the file that I provided above

                

Fatal error:  Class 'EB' not found in /home/etial/public_html/administrator/components/com_widgetkit/plugins/content/easyblog/views/edit.php on line 10

How to include class EB in other php file?

I am sorry but we will not be able to assist you with further customization questions.
