Shopify Theme Modified

We are a Personalised jewellery gift store based in the UK offering a range of products that the customer can customise into a unique gift.

Our current theme has had some work done to it already however it's going to need amending and making it look more professional.

What we require are as follows:

Slidder/banner need to be optimised to work on mobile device. Completion of slider/banner on website to include selected images and text.

We need product categories adding in, for example a drop down on mobile device and heading on desktop.

Personalised customisations need completing which includes ensuring all options are included in a drop down selector for existing products.

Personalised customisation - functionality to include new customisation for new products.

Product names need to display properly on preview and not cut off like it does currently.
