Hey RGB,
I will go over the questions in the same order:
1). By design the “See All” button on portfolio sections as part of one-page template should lead to the original portfolio page, and so far no problems have been reported with this mechanism. Could you please provide the URL of your website so that I could have a look at the particular code? Thanks!
1b). It is possible to create a list of instances of a particular post type in WordPress, although Kanso does not provide this functionality out-of-the-box. Please take a look at this third-party plugin, it might do what you need.
2). At the moment the showing/hiding of portfolio captions is done using jQuery rather than CSS; the respective code can be found under the “Overlay image for posts” title in the “header-functions.php” file (lines 405-421). To change the transition, you need to replace the “FadeIn()” on line 413 and “FadeOut()” on line 416 with an effect of your choice.
3). This is not envisaged from the back-end of the theme, but can be achieved by moving the code that is responsible for showing the filter; the code on lines 165-180 of the “page_one-page.php” template file should be moved after line number 114. In case you’re not familiar with php, I highly recommend asking for a professional’s help with this one (e.g. on Tweaky.com).
4). The full-width Google Map in the “Contact” section of the demo is just an image :) You can upload a header image for each individual page from the “Page Settings” box while in the page editor mode.
Please let me know if any of the issues requires clarification.
Sincerely,
