The Options Combination popup consists of the form for selecting option combinations and its properties and a grid of defined options combinations. A combination is a selection of given option values, such as "Color: white, Size: medium, Height: tall". The option combinations may be used when the product option selection mode is set to "Listing" or when selection mode is "Selection", but special pricing applies to one or more of possible combinations, or one or more of possible combinations is not available.

The option combination form has two sub-sections - "Combination" and "Properties". The first subsection contains all product options except Text box and Text area (because the values cannot be defined for these option types). The section will list all the options with their values in the same way as the options are presented on the front end when selection mode is set to "Selection". For drop-downs and radio-buttons the drop-down fields will be displayed and extended with a special option value - "ANY". If the special value "ANY" is selected the system will try all available option values when adding/editing option combination. If the selected combination already exists it will be updated with the new properties (see below), if the combination does not exist it will be created.

• Available - controls if the option combination is available for purchasing or not. This property may be used to set the combination as "not available" even when product option selection mode is set to "Selection". Note that when option selection mode is set to "Listing" the combinations marked as "not available" will still be displayed on the front end, however the system will not allow adding them to the cart.
• Price Modifier Type - controls how the price of the selected combination should be adjusted. If set to "Equals", the price of the combination will override any other price settings (price brackets, other option value pricing). If set to "Flat", a discount or surcharge (depending on the sign of the "Price" field) will be applied to the base price of the product, along with the price adjustments of each option in the combination (which can be changed by editing the individual options). If set to "Percent", the discount or surcharge will be applied as a percentage of the base price. The percent value in the "Price" field should be an integer.
• Price - the price modifier value, may be negative. This field is required, but may be set to 0 with "Flat" or "Percent" modifier type, if no price modification is necessary.

Add/Save button should be used to create a new combination or to save an existing combination after editing. To edit an existing combination double click on it in the grid below the form.
Note that option combinations should be revised after adding, removing or modifying options or their values, otherwise the combinations may become inconsistent with the options.

The toolbar of the popup contains the following buttons:

• Close - closes the popup, note that modification will take place only after clicking "Save" button for the entire product (just like on any other product tab).
• Delete - deletes the option combinations selected in the grid
• Move up/down - adjusts the numerical priority of the combinations. The priority is used for sorting the combinations on the front end, and it is relative to each product.
