At the moment in [url removed, login to view] the display of categories is not very well solved. There is some navigation possible but the status is, that the choices of categories are very limited. This was nice to start with, but for an professional search functionality it is not well enough.
This Category Tree has to be modified with Ajax. While clicking on an Category the next lower category level (all entries) will be displayed with the number of entries. Always 1 level above the last clicked category will be displayed also. In the bottom line exist an field to collapse the whole tree or to open it completely. It is important to make sure that the field in which the categories are being displayed will grow with the content just by setting the next field deeper or higher.
Of course the clicking on the categories will have also implications for the displayed search results similar as it does already now.
In order to speed the navigation up the category structure of any supported ebay-domain has to be stored in the mysql-database. Because of the fact that ebay changes the category structure from time to time any week the category tree has to be verified with an cron job running on the engine. Changes will be inserted in the database. Of course no articles have to be stored in the database (they will be always taken directly from ebay).
In the category statistics an additional row will be included which displays the category in which the item has been displayed. If display was over all categories the category will be displayed as “all” else the deepest category which included all searches will be displayed, means that as a sample if an user searches for “Washington” and is looking for this in the stamps tree in the “US Stamps”-Category it will be displayed “Us Stamps”. When clicking on the title of the row the content of the whole list will be sorted after the content of this row ascending, by clicking again – descending. On mouse over the category name an little field appears which displays the whole category tree in which the category stays – as a sample “Stamps/US Stamps/...”
Clarification: User do not have to register but just to search for some terms like "Nintendo" in the Search Engine and then the Category tree will be built out of the response of Ebay... unfortunately right now only some results are being displayed in the category tree as you mas see when you compare the findings of the main category with the number of findings in the sub categories
You will get an complete backup backup of the actual page and have to develop the solution on your own server, only after I have tested it on your server you may install the solution on mine - of course it has to work there also. I work with GAF Escrow system only. Bids proposing any other proceeding will not be considered.
The whole description and also some screenshots to clarify you may see in the enclosed pdf whose content is also part of the work you may bid on
