Overview

This country and language project for Sealed Air updated the translations modal to the new POP design system and e-commerce requirements. An accessible selector needed several iterations — and it became a catalyst for changing the entire navigation so modals could live in the header without fighting the menu.

01

The challenge

Shoppers around the world needed to change country and language reliably. The selector also controlled which products were available, so a broken pattern could stop a purchase.

02

The approach

Competitive research, component variants, and breakpoint designs in Figma — then a full rethink of the mobile header once the first footer-toggle pattern failed.

03

The impact

Desktop and mobile experiences moved into staging as a defined modal in the design system, and the work realigned navigation going forward.

What we achieved

Region-only

Starting point

The previous modal only changed region

2 fields

Country and language

Site destination and content language, separately

Responsive

Every breakpoint

Utility nav on desktop through mobile

Design system

Defined modal pattern

Added after staging tests

The problem

The country and language selector is an integral piece of the Sealed Air web experience. Users from across the globe need to change the region, country, and language they associate with. The feature also corresponds to which products are available, so it can disrupt shopping if it is not addressed correctly.

“As a user I want to be able to select the country site that I want to go to as well as the language that I want for the content to be displayed in.”

Areas of opportunity

The previous modal only required regional changes. A few key areas needed focus:

  • No selection state

    Choosing a region did not show a clear state change, so people could not tell what was current.

  • Weak hover states

    Links lacked usable hover feedback, which made the list feel inactive.

  • Ambiguous click targets

    Categories and links were styled the same, but not everything was clickable.

  • Unclear regional IDs

    Codes like AM and EMEA did not help someone choose a country or language.

  • Unstyled header

    The panel had no designed header row for an exit control or dropdown.

The previous Sealed Air language selector: a region list on mobile and a desktop popover with Americas, EMEA, and language codes.

Research approach

I researched standard practices for region and language selectors. I focused on e-commerce sites and indirect competitors, because most direct competitors did not provide strong examples. The patterns that stood out separated region and language from each other.

  • Separate the two choices

    High-usability examples let people pick a country site and a content language as distinct fields, not one mixed region list.

  • Nielsen Norman Group

    Their guidance on locale selectors helped me sort common pitfalls from patterns worth carrying into POP components.

  • Utility nav, not primary nav

    The selector needed to sit with account and locale tools on desktop, then get a mobile pattern that did not collide with the main menu.

Design process

I started by creating components that matched the new navigation and the competitive analysis. I wanted the language selector in utility navigation on desktop, but mobile still needed a solution.

  1. Step 1

    Component variants

    What changed

    I used variants for hover and selected states and added a flag so the current country was recognizable at a glance.

    Design intent

    Build the locale control as a system piece first, then place it — not the other way around.

    Figma variants for locale chips, country fields, flag lists, and a You’re in change control.
  2. Step 2

    An early mobile miss

    What changed

    The first mobile pattern put the selector in a footer toggle that revealed from the bottom. The full-screen exit icon overlaid the original main menu, which made the header feel like two products at once.

    Design intent

    The modal needed a header that could host overlays. That meant redesigning the mobile menu chrome, not just the locale form.

    Early mobile menu with a footer You’re in change toggle, a language and country modal, and a country list.
  3. Step 3

    A scannable country list

    What changed

    I designed a dropdown with hover states and flags. The first shipped iteration would use native dropdowns for accessibility; the custom list showed how people could scan countries later.

    Design intent

    Native controls first for access, with a designed list ready once the pattern was proven.

Desktop design

Once testing identified the pattern, I designed every required breakpoint and built responsive Figma components from desktop to mobile. I created states for categories, subcategories, and list items, updated the utility navigation bar, and built high-fidelity prototypes for menu interactions and animations.

Mobile design

To fix the overlapping modal, I tried a version with padding from the screen edges so it sat on the hero instead of the main menu. That helped, but as the mobile navigation evolved, so did the modal.

As a team we decided to address the modal experience as a whole. This project became a catalyst for changing the entire navigation going forward.

Mobile flow from the SEE menu into an inset language and country modal, through a country-specific warning and an enabled Continue action.

Moving forward

Desktop and mobile experiences moved into staging for development and testing. I am confident these designs improve the selector — and they also aligned the navigation. Once tested, they were added to the design system as a defined modal experience.
