jquery/js scripts to fix on page

Hi, I need a jQuery/javascript/front-end expert to fix and finish some stuff on the following page: [login to view URL] Scripts used on website: — Flickity for Sliders ([login to view URL]) — jQuery SmartTab for Tabs ([login to view URL]) — All JS and configuration for scripts ([login to view URL]) TASK #1 After scrolling for 160pixels, <header> navigation should be fixed on top and the rest of the page should scroll below. This is EXACTLY what we want to achieve: [login to view URL] . Here are the visual layout (as a reference): [login to view URL] [login to view URL] TASK #2 On the top navigation, clicking on the link “Inovação” should scroll down and open the second tab of #tabs (the one that says “inovação tecnológica)”. I need this to be possible to duplicate for other tab links. This is probably the reference link for implementation: [login to view URL] TASK #3 There seems to be a conflict with SmartTab and Flickity sliders. On the $#tabs and #tabs02 sections there’s two different tabs: “sustentabilidade/inovação tecnológica” and “serviços/produtos”. Inside all this tabs is a FLickity slider but when switching between them, the slider doesn’t work and/or disappears. It gets worse if a “resize” is pulled because SmartTab isn’t calculating Flickity’s height.
