Hi [~devanshu.vyas]

I agree, this method to rendering the pagination is a pain.

Instead a input box we can use this pattern :

[Begin] ... [viewIndex-2][viewIndex-1][viewIndex][viewIndex+1][viewIndex+2] ... [End]

Display Example for a list with 40 pages :
 * on page 1 : *1* 2 3 ... 40
 * on page 15 : 1 ... 13 14 *15* 16 17 ... 40
 * on page 38 : 1 ... 36 37 *38* 39 40
 * on page 40 : 1 ... 38 39 *40*

For a number page greater that 100, I'm in favor to stop and set 99+
 * 1 ... 13 14 *15* 16 17 ... 99+

Maybe on this case we can set a input box after the '99+' but inn general a huge pagination isn't manageable by human so it's better to restart the search with more constraint in filter or thinking about a consolidate screen

On other idea for the pagination would be the infinite scroll but is't premature at this time.

> Recently, I came across a situation where an entity was taking too much of a time(browser asked me to either wait or kill) while loading/searching results in the Webtools application. The entity had close to 5M records, and I checked the server responded timely but the rendering of the screen was taking time.
> When I explored the issue I came across a macro which renders the pagination on the screen, and it had a code block which was causing the screen rendering delay.
> {code}
> <#assign x=(listSize/viewSize)?ceiling>
>   <#list 1..x as i>
>     <#if i == (viewIndex+1)><option selected="selected" value="<#else><option value="</#if>${i-1}">${i}</option>
>   </#list>
> {code}
> This code seems logical enough to me, and what I gather from this is that the list will render a select box with 250,000 options. 
> I would like to propose a change in this UI/UX from select box to an input text box so a user can navigate to any page, similar to a navigation input box in a PDF document reader application.
> Please let me know your thoughts on this and share some more ideas to how we can improve/resolve this issue. Looking forward to your replies!
